Abstract
Improvements to the High Speed Uplink Packet Access (HSUPA) scheme have been made. Among the three main aspects, providing Optimized Rate Request Reporting, providing Signaling for Lower Delay Delivery, and providing a MAC-e PDU Format for Control Information, the Signaling for Lower Delay Delivery may be considered as the main improvement, while the other two aspects can be supplementary improvements.
Claims20
A method of signaling between a base station and a network controller, comprising:
- detecting at least one radio transmission failure based upon a number of radio transmission retransmissions that occurred;
- and
- providing information to the network controller regarding the detected radio transmission failure to allow further signal processing thereafter.
A method of signaling between a base station and a network controller, comprising:
- receiving a radio transmission failure indication based upon at least one radio transmission failure that was detected based upon a number of radio transmission retransmissions that occurred;
- and
- performing further signal processing according to the received radio transmission failure indication.
A method of improved High Speed Uplink Packet Access signaling in a communication system with User Equipment and a network controller, the method comprising:
- providing information to the network controller regarding radio transmission failures based upon a detected number of radio transmission retransmissions that occurred;
- and
- preventing unnecessary Protocol Data Unit discarding based upon the provided information to thus increase data throughput by minimizing delays due to performing scheduling at the User Equipment, performing HARQ retransmissions, performing lub interface signaling, and/or performing re-ordering at the network controller.
